Filed: 1979-05-16
Abstract: PURPOSE:To reduce the dispersion of electric characteristics by forming a transformer by a high-voltage coil which is divided into three sections and three diodes, making the voltage of the second-layer coil 35% and less of the anode voltage, and to make the coil approximately out of tuning. CONSTITUTION:Three hight-voltage coils 6-8 are connected in series with diodes 9-11 being intervened. A focus voltage is taken out of the first-layer coil 6 via a bleeder resistor 12, and an anode voltage is taken out of the third-layer coil 8. The voltage that is 35% and less of the specified anode voltage is taken out of the second-layer coil 7. The number of turns of the second layer coil is so constituted that the 11th harmonic wave can be taken out. Since the ripples of the focus voltage can be reduced, and the second-layer coil 7 can be regarded as approximately out of tuning, only the first- and third-layer coils interfere to each other, and the dispersion of the electric characteristics is reduced accordingly.

Abstract: PURPOSE:To reset the object being controlled rapidly when it moved further from the specified position by controlling a driving means based on the DA conversion output of a counter for moving position detecting pulses. CONSTITUTION:When the player is stopped, a counter 34 which is started by the stop instruction signal when a tone arm 1 being the object being controlled passes by the specified stop position owing to inertia begins to count the pulse signals P from a detecting circuit 32, but the arm 1 turns in the arrow a direction and therefore the counter counts up based on the discrimination signal S of high level indicating the turning in the a direction. This output is made to an analog voltage E in a D/A converter 35 and is then applied to a horizontal control circuit 36, causing such a voltage which turns the arm 1 in the arrow b direction to be applied to  a coil 10. Next, when the arm 1 turns in the b direction, the counter 34, is counted down from the count value by the discrimination signal of a low level, causing such a voltage which turns the arm 1 in the a direction to be applied to the coil 10. This is repeated to let the arm 1 stop rapidly in the specified position.
